Struct Skeleton 

pub struct Skeleton<const N: usize> {
    pub bones: Vec<Bone, N>,
}

A hierarchical skeleton with bones.

The generic parameter N specifies the maximum number of bones.

Fields

bones: Vec<Bone, N>

Implementations

impl<const N: usize> Skeleton<N>

pub fn new() -> Self

Create a new empty skeleton.

pub fn add_bone( &mut self, bone: Bone, parent: Option<BoneId>, ) -> Result<BoneId, ()>

Add a bone to the skeleton.

Returns the bone ID on success, or an error if the skeleton is full.

pub fn get_bone(&self, id: BoneId) -> Option<&Bone>

Get a bone by ID.

pub fn get_bone_mut(&mut self, id: BoneId) -> Option<&mut Bone>

Get a mutable reference to a bone by ID.

pub fn update_transforms(&mut self)

Update world transforms for all bones based on hierarchy.

Must be called after modifying any bone transforms and before skinning.

pub fn compute_inverse_bind_poses(&mut self)

Compute inverse bind pose matrices for all bones.

Should be called once after setting up the skeleton in its bind pose.

pub fn get_skinning_matrix(&self, bone_id: BoneId) -> Matrix4<f32>

Get the skinning matrix for a bone (world_transform * inverse_bind_pose).

Trait Implementations

impl<const N: usize> Clone for Skeleton<N>

fn clone(&self) -> Skeleton<N>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const N: usize> Debug for Skeleton<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const N: usize> Default for Skeleton<N>

fn default() -> Self

Returns the “default value” for a type.
